A kezayis isn't directly a shiur on the maaseh, it's a shiur on the
cheftza. Less than a kezayis isn't okhel.
So when a speicific din refers to a mashehu of food can't be literally
a crumb.
So fasting, which is avoiding consumption, chatzi shiur assur min
haTorah. But chameitz, less than a kezayis is a derabbanan becuase
asi le'itztarufei. Or basar bechalav -- one may get hana'ah from less
than a kazayis. (Yes, I picked to cases that involve okhel but not
akhilah on purpose.)
Generalize that, and maybe you have a tool to help you think through the
question of "is this mashehu literal?"
1- Does this issur refer to a specific kind of object?
2- Does that object have a minimal size?
Or maybe not. Maybe it's *only* the noun "okhel" that has a minimum size.
Other cases aren't crossing my mind right now.
Tir'u baTov!
